What is the standard of good anti-static work clothes
First, the performance of high-quality anti-static work clothes must meet the standards
It is said that clothing with antistatic performance is antistatic work clothes, but it does not clearly indicate what standard represents antistatic performance. In fact, it is clearly stated in the national standard GB12014-2009 that the surface resistivity is 10 to the 5th power. Antistatic performance is considered between 10 and 11th ohms, and antistatic workwear is no exception. In addition, in order to distinguish the performance of antistatic workwear, it is divided into Class A and B, and the surface of Class A antistatic workwear. The resistivity range is from the 5th power of 10 to the 7th power of 10, beyond the 7th power of 10, and those that include the 7th power of 10 are class B antistatic work clothes.
Second, high-quality anti-static work clothes work better
High-quality anti-static work clothes are more sturdy and durable, so there are requirements in workmanship. In GB12014-2009, it is stipulated that the sewing lines of various parts of anti-static work clothes are straight, neat, and flat. The upper and lower are suitable for tightness, there should be no stitches at the needle jumper, thread breakage and landing needle. The stitch pitch: (12 ～ 14) needles / 3cm (unit area mass ≥200g / m2), (14 ～ 16) needles / 3cm (Unit mass area <200g / m2), and the seam strength of the anti-static work clothes must not be less than 100N.
